我正在尝试使用ionic 3发布一个Android应用程序，但运行

这些错误显示：

我有同样的问题，我已经使用了android@6.3.0，但它没有解决我的问题。
要解决此问题，我会关注该消息并将条目移到META-INF之外。该应用程序似乎没有此操作的问题。

我解决此问题的方法是重新安装android
ionic cordova platform remove android
*注意，其中一个插件无法在最新版本的android上运行。所以，我必须将Android版本降级到6.3.0
ionic cordova platform add android@6.3.0
希望这也有助于其他人！
